Guess what these are!!!!!!!!!!
They are stackable colanders from Rösle, I found them while I was shopping at the divine Milanese design store DePadova .......... a must stop for all design lovers!!!!!
Think stainless steel with rubber sides that can be pushed down ....... not a great description but, think of those paper chinese lanterns that flatten or an accordian!!!! Anyway, they stack within each other and are great design ......... or, maybe I have just been in Milan toooooo long!!!!
These are great! I found them in the US at Didriks.com - free shipping in the continental US
